To a wlmm it may concern:

Be it known that I, Mama. G. TouMo, a citizen of the United States, anda resident of New York city. in the county and State of New York, haveinvented certain new and useful Improvements in Closures for Containers,of which the following is a specification.

This invention relates to stoppers for containers of various kinds andis particularly designed for collapsible tubes of thin sheet metal.

The object of the'invention is to provide a closure of this character inwhich'the cap can be applied by direct pressure downwardly, withoutturning or screwing, and will be retained by the resiliency of the sidewalls of the cap; and which cap is pro vided with a resilient liner orplug that will be compressed at the opening in the container end andsecurely close the container; and which cap can be readily removed andreplaced when desired on the container.

The accompanying drawing showing one embodiment of my invention, Figure1 shows the cap about to be applied to the container.

Fig. 2 shows the cap secured on the container.

Fig. 3 is a plan view partly in section.

Fig. 4; shows the cap in elevation, broken away at the bead.

Fig. 5 shows the tube top portion.

Fig. 6 shows the liner plug.

Fig. 7 is a cross section through the tube top and cap, above the beadpartly applied and flexed.

The device as shown comprises a cap 2 of the usual cylindrical formhaving an'end wall 3 closing the top and,- preferably a bead at the top,forming a groove 5 on the inner wall. This cap that is made of resilientmetal, is provided with a bead 6. at

the lower end, as by rolling the edge of the cap. which bead extendsinwardly.

The container 7 as shown is of the collapsible tube form with a rigidmetal disk 8 at the top. This disk has aset of ribs 9 extendingoutwardly from its outer side, of which four are shown. At the bottom ofeach rib 9 is a groove 10 extending laterally. The disk 8 has a smallbore ,11 at the upper end, that is formed somewhat conical as shown at12. It is to be understood that the closure can be applied to any formof a the disk 8 until the grooves 10 are reached I by the bead 6 on thecap, whereupon the cap will spring inwardly to its former or normalshape, and the head will enter the grooves 10 which will permit the capabove the head to engage the outer side of the ribs above the grooves,as indicated in Fig. 1. This will cause the cap to be securely retainedon the disk, but it can be withdrawn by pulling it outwardly, assistedpossibly by compressing the cap inwardly at opposite sides between theribs.

For the purpose of securely sealing the contents of the tube againstescape into the cap, I provide a sealing liner or plug 13 of suitablematerial, such as soft rubber. This is somewhat crescent-shaped with alower extension 14. The upper and outer margin of the plug is of a sizeto enter the groove 5 at the top of the.cap,'tha-t will retain the plugas a. liner in the cap, but its concave upperface will normally extendaway from the top 3 of the cap a considerable distance. A slightdepression or bore 15 may be formed in the upper wall of the cap at thecenter. The plug is so shaped that whenthe closure is applied the lowerextension 14 will seat on the conical disc top 12. As the cap ispusheddown the liner will be forced toward the top 3 of the cap. Thiswill tend to flatten the convex portion of the liner, that will beassisted by the de ression 15, and when the cap is pushed own to engathe head with the grooves, the part 14 o the liner will be very tightlypressed against the conical end 12, and securely seal the opening intothe tube.

A device of the character is very simple in construction, comprisingmerely a cap of sheet metal, the liner plug of rubber, in connectionwith the "disk -8 provided withthe ribs and forth.

grooves, and also the neck as set no lVhat I claim is:

1. In combination,.a container having the neck provided with a series ofupright ribs on the outer side, each rib having a lateral groove at thebase, a cap of resilient metal provided with a bead at the lower edgeprojecting inwardly, the bore of the cap' having a diameter adapted tosnugly fit the said neck at the rib portions, whereby the cap can beapplied to said neck and be expanded by said ribs until the bead willreach the grooved portions of the ribs, whereupon return of the cap tonormal shape will cause the bead to enter said grooves and lock the capon the neck.

2. In combination, a container having the neck provided with a series ofupright ribs on the outer side, each rib having a lateral groove at thebase, a cap of rcsilent metal provided with a bead at the lower edgep'rojecting inwardly, the bore of thocap having a diameter adapted to,snugly fit the said neck at the rib portions, whereby the cap can beapplied to said neck and be expanded by said ribs until the head willreach the grooved portion of the ribs, whereupon return of the cap tonormal shape. will cause the bead to enter said grooves and lock the capon the neck, a liner plug of crescent shape placed inside of: the capengaging the upper portions of the cap, which plug compressed againstthe said neck on appli' cation of the cap.

3. In combination, a container having the neck provided with a series ofribs on. the outer cylindrical side, and a reduced bore at the neckextending downwardly from the upper edge, each rib having a lateralgroove at the base, and a. closure cap of resilient metal provided withan annular groove in its inner wall at the top and a bead on the loweredge that projects inwardly, the bore of the cap having a diameteradapted to snugly fit said neck at opposite rib portions, whereby thecap can be applied to said neck and be expanded by said ribs until thebead will reach the grooved portions of the ribs, whereupon return ofthe cap to normal shape will cause the bead to cnter'said rib groovesand lock the cap on the neck, a resilient liner plug of, substantiallycrescent shape placed inside of the cap with its outer upper marginengaging the said groove portions of the cap, said neck being conical atthe'top, said resilient plug having its lower face compressed againstsaid neck top on application of the cap. i

4. In combination, a container having the neck provided with a series ofribs on the outer cylindrical side, and a reduced bore at the neckextending downwardly from the upper edge, each rib having a lateralgroove at the base, and a closurecap of resilient metal provided with anannular groove in its inner wall at the top and'a head on the lower edgethat projects inwardly, the bore of the cap having a diameter adapted tosnugly fit said neck at opposite portions, whereby the cap can beapplied to said neck and be expanded by said ribs until the head willreach the grooved portions of the ribs whereupon return of the cap tonormal shape will cause the head. to enter said rib grooves and lock thecap on the neck, a resilient liner plug of substantially crescent shapeplaced inside of the cap with its outer upper margin engaging the saidgroove portions of the cap, said neekbeing conical at the top, saidresilient plug having its lower face compressed against said top onapplication of the cap, said plug having a central opening at its upperface to cause compression of the plug.
